How to prevent personal electric shock accidents caused by leakage of street lights or advertising l

In order to prevent personal electric shock accidents caused by leakage of street lights or advertising light boxes, we can take the following measures:

1.Regular inspection and maintenance: Conduct regular inspection and maintenance of street lights and advertising light boxes to ensure the normal operation of their electrical equipment. The inspection includes checking whether the wires, plugs, switches, etc. are damaged or aged, and replacing or repairing them in time.

2.Install leakage protector: install leakage protector in the circuit of street lamp and advertising light box, once leakage occurs, leakage protector will automatically cut off the power supply to avoid electric shock accidents caused by current passing through the human body.

3.Strengthen insulation measures: insulate the wires, plugs and other components of street lamps and advertising light boxes to ensure that the current does not enter the human body through the insulating material and reduce the risk of electric shock.

5.Increase monitoring and alarm system: install surveillance cameras and alarms around street lights and advertising light boxes to monitor and alarm in time, and take timely measures to avoid accidents once abnormal situations occur.

6.Strengthen training and publicity: Carry out safety training for maintenance personnel of street lamps and advertising light boxes to improve their safety awareness and operation skills.

At the same time, through publicity activities, the public is popularized with electrical safety knowledge, the public's safety awareness is enhanced, and electric shock accidents are avoided due to inadvertent contact with electrical equipment.

In short, to prevent personal electric shock accidents caused by leakage of street lamps or advertising light boxes, it is necessary to consider comprehensively, starting from regular inspection and maintenance, installation of leakage protectors, strengthening insulation measures, strengthening safety warnings, increasing monitoring and alarm systems, and strengthening training and publicity, etc., to ensure the safe operation of electrical equipment and reduce the occurrence of electric shock accidents.

Wait for static electricity or should be charged to confirm the leakage phenomenon, please connect it in time.

1. How to ensure the safety of street lights?

The fundamental solution to the safety of street lamp electricity is to install leakage switches, only the installation of leakage switches can make the street lamp power distribution meet the national standards, in order to protect the safety of the public, in order to protect the safety of our management units!

National Standard 1: GB50057 "Design Code for Low-voltage Power Distribution", which stipulates that the ground fault occurs in the event of indirect contact, the TN-S system should be cut off within 5S and the TT system should be cut off within 1S. Only leakage switches can meet the requirements of the national standard.

National Standard 2: GB13955 "Installation and Operation of Residual Current Action Protection Device", which stipulates that outdoor electrical equipment should be installed with residual current action protection device, that is, leakage switch.

2. How can the leakage switch be installed?

In order to install the leakage switch, it is necessary to eliminate the leakage point on the street lamp line, measure the insulation resistance of the line and lamp through the high-precision digital insulation meter, and replace the cables and lamps with insulation faults. As long as the insulation resistance of the entire line (with load) is increased to 20K, the leakage switch can be installed.

3. How to ensure the stable operation of the leakage switch and ensure the lighting rate?

1.The joint should be waterproofed, otherwise the leakage switch will operate normally on sunny days, and it may trip on rainy days.

2.The lamp pole does secondary leakage protection for the lamps and lamp wires, so that the failure of one lamp will not affect the lighting of the whole road.

3.Split-phase over-current protection, separate over-current switch for each phase wire.

4.Leakage switch selection, electromagnetic type, 300mA, automatic reset function.

Leakage monitoring equipment can be installed, which can monitor zero sequence current and leakage voltage, and remotely control the power shutdown of the line, which can accurately locate the leakage point.

Solar street lights use low voltage 12V or 24V, low voltage is safer.
